I have added a backport repository to apt's sources.list to get an application:

deb http://ftp.uk.debian.org/debian/ wheezy-backports main

Long story short: I did not manage to install the application properly so I gave up and removed that line from my sources.list.

But since then apt is a mess. For some reasons, gnome has been partially uninstalled in the process (I played with synaptic and aptitude and apparently made a mistake) but I can't reinstall it:

sudo apt-get install gnome

....

The following packages have unmet dependencies:
gnome : Depends: gnome-core (= 1:3.4+7+deb7u1) but it is not going to be installed
     Depends: nautilus-sendto (>= 3.0) but it is not going to be installed
     Depends: gimp (>= 2.8) but it is not going to be installed
     Depends: hamster-applet (>= 2.91.3) but it is not going to be installed
     Depends: gnome-applets (>= 3.4) but it is not going to be installed
     Recommends: browser-plugin-gnash but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I have tried (in many different orders):

apt-get update
apt-get upgrade
apt-get dist-upgrade
apt-get clean
apt-get -f install gnome
apt-get install -f
dpkg --configure -a

but none of these worked.

I have also run sudo dpkg --get-selections | awk '{if ($2 == "hold") print $0;}' to find out more about the held packages but it returns nothing.

What is the output of apt-get -f install? Also, list apt-cache policy pkgname1 pkgname2 for the packages that are mentioned in the error message. –  Faheem Mitha Mar 7 at 15:20
    
Odd, looks normal. Output of dpkg -l for the same packages as apt-cache policy, please. –  Faheem Mitha Mar 7 at 15:50

After some discussion in chat, it became clear that the problem was that

apt-get install gnome

did not work on an apparently normal wheezy system. The install attempt exited with the errors given in the question.

The culprit turned out to be www.deb-multimedia.org. After removing the deb-multimedia lines from sources.list, the install proceeded successfully.

The problem was not that the deb-multimedia lines were in sources.list, but that the deb-multimedia were not at a lower priority. For anyone reading this, be aware that the deb-multimedia maintainer does not attempt to keep compatibility with Debian, so having those sources available at the same priority as the Debian archive may cause problems. More generally, this is a good defensive measure for any third party repositories which do not pin themseleves at a lower priority server-side. Putting the deb-multimedia sources at a low priority like 1 should not cause any problems in normal usage. A stanza like

Package: *
Pin: origin www.deb-multimedia.org
Pin-Priority: 1

in /etc/apt/preferences should suffice.
